Deckard is a Blade Runner, a police man of the future who hunts down and terminates replicants, artificially created humans. He wants to get out of the force, but is drawn back in when 4 "skin jobs", a slang term for replicants, hijack a ship back to Earth. The city that Deckard must search for his prey is a huge, sprawling, bleak vision of the future. This film questions what it is to be human, and why life is so precious.
